Been getting CEL for O2 down stream sensors after two or three track sessions. Saw where Bosh has a wide band sensors that are said to send more detailed signal to ECU other than "too rich/too lean" Any body used these? Are they better than OEM

Just a thought, I had the same code come up last year but it turned out to be the wires leading to the senors had melted onto the exhaust header. Maybe check all the wire routing first before buying new ones. It's a bit tight down there and the harness clips can come off.Been getting CEL for O2 down stream sensors after two or three track sessions.

Its only after running on track so seems like if it were harness it would be all the time. From what I have read, track days can kill sensors. Mine are originals, 35k miles but 10+ years old now. So questions still is are wide band better than OEM?Just a thought, I had the same code come up last year but it turned out to be the wires leading to the senors had melted onto the exhaust header.
